东南沿海地震区地震活动特征及未来趋势研究

The Seismicity Charateristics and the Trend of the Coming Macroseism in the Southeast Coastal China

一、引言迄今,我国学者关于东南沿海地震区实际范围的界定大同小异,为了便于研究与应用,本文主要采用马宗晋等对该区范围的基本看法.所谓东南沿海地震区,系指北起福建、南至海南岛,包括广东、广西等省区及其附近海域所形成的地震活动区.它是中国东部第二个地震活动性较高的地区。

In this paper,on the base of the outlining for the seismo-geological structure and the charateriseics of the tectonic stress field in the Southeast Coastal China,the basic feature of the seismicity and the trend of the coming macroseism in the above-mentioned region are studied preliminarily.The results show that since 1400's,there have been undergone tow seismic activity periods in the Southeast Coastal China,the first seismic activity period was from 1400 to 1695,and the second begin at I696,s,and would end in 2031 or so.
